don't voice your opinion on punishment, if you follow through with it willingly and behave properly, chances are he'll appreciate it
unless you have some sorta drunkard as a dad, but usually people with those fathers are mean, and you're not mean
unless it's something like "go outside and don't come back until next Monday"
but even then don't tell him your opinion, go to your neighbors and ask if you can use their phone to call the police or a nicer relative
